Using the program, undrained and drained triaxial tests, cyclic triaxial tests, undrained cyclic torsional tests are simulated and a three-dimensional site dynamic response analysis is also performed. After testing the calculation stability, the implemented schematics allow subzones of the mixed discretization process in FLAC3D share mapping center and simultaneously enter and leave liquefaction status. According to requirements and procedures of user-defined-model (UDM), the plasticity model is successfully implemented into FLAC3D code in Visual C++ environment. A state parameter for compatibility with critical state soil mechanics enables the simulation of sand at various densities and confining pressures with a same set of parameters.

Based on the physics of large post-liquefaction deformation of sand, a bounding surface plasticity model with appropriate mapping rules for plasticity and dilatancy in three-dimensional stress space is developed.

The purpose of the study is to improve the simulation of liquefaction of sands and variations in effective stress when using FLAC3D for the dynamic analysis of liquefiable ground and structures.
